Geo Google get different items

I have the codes below to get full address from Geo API google. It works fine
but now I need to get address, city, state, and zip. And I have no idea how to get them in c#.
I read the following article as well but it is in javascript

        public static string GetAddress(string latitude, string longitude)
        {
            string locationName = "";
            string url = string.Format("https://maps.googleapis.com/maps/api/geocode/xml?latlng={0},{1}&sensor=false&key=AIzaSydsfBzalHtsdfsadfsadfasdfdsafTxZaIVQrePIK_Lfbv1QqPC_Xr5c", latitude, longitude);          
            XElement xml = XElement.Load(url);
            if (xml.Element("status").Value == "OK")
            {
                locationName = string.Format("{0}", xml.Element("result").Element("formatted_address").Value);                             
            }
            else
            {
                locationName = xml.Element("status").ToString();
            }
            return locationName;
        }
